After an introduction discussion of the conceptual meaning of electrocatalysis and its technological significance, the compact of electrochemistry on the environment is illustrated with two major examples: Hg cells in chlor-alkali technology and electric cars. The problems of fossil fuel exhaustion and pollution call for a resort to renewable energy sources. Electrochemistry can help to alleviate environmental issues with appropriate technological strategies involving processes and products. In this context, research on electrocatalysis has been focused on a number of major targets which are discussed and illustrated by means of examples: intermittent water electrolysis; destruction of organic pollutants; ozone, hydrogen peroxide and chlorine dioxide electrosynthesis; cathodic conversion of CO2; anodic oxidation of SO2; cathodic destruction of NOx; replacement of chromates; desulfurization of natural gas, etc.
